HAT-CLIPPING MACHINE.

Original No. 1,452,048, dated April 17, 1923, Serial No. 422,205, filed November 6, 1920. Application for reissue filed September 20, 1927. Serial No. 220,781. i a i i This invention relates to an improved machine for clipping hats made of velour or similar material, such hats being formerly clipped as a hat body before it was formed with a brim, by passing it through machines that clipped itin flat form, orv hand clippers havebeen slowly passed over the outside of the hat, in which case the degree of finish depended very much-on the care or thor' oughness with which the operator did the work. a I

The invention is designed to provide a machine which clips the hat body quickly over its entire surface, and is also designed to leave no portion thereof unclipped, the manual operation necessary being only such as will start or stop the machine and inserting or removing the hat,

The inventionis designed to provide a machine of this kind in which clipping devices are brought ,to bear on a hat body which is supported so that it rot-ates, the

parts being constructed so that theyv are movable relative'to each other in order that the clipping devices may traverse the entire surface of the hat. I prefer to arrange the clipping devices so that, one of them clips the crown, another the top of the brim and another thebottom of the brim. h

I'lhe invention is further designed to provide a machine of this kind in which the arrangementof the parts is such thatthe ma chine is compact and small, and in which the clippings are carried from the machine, and also to provide. for :1 raising of the nap of the velour-or similar fabric so that an even cut is broughtabout during the clip-,

ping operation.

The invention further consists of certain details of construction which will be hereinafter more fullydcscribed and finally embodied in the claims. t v V The invention is illustrated in the accompanying drawing, in which Figure l is a front view of one form of my improved machine, and FigureQ a detail. of a portion of the niechauisnii that ings the hat support. Figure 3 is aside view of the machine shown-i. Figure 1. Figure i is a top view somewhat diagran'imatic, showing the manner in which the hat is swung so that all its parts come in contact with the clipping device. Figure 51 5 a'horizontal section of one of the clipping devices with a rotary cutter shown partly in elevation, such section being taken on the line 55 in Figure 6. Figure 6 is section taken on line 66 inFigure 5. Figure 7 is a detail section taken on line in Figure 5, and Figure 8 is an elevation of one side of the floor plate of the clipping device.

The machine as illustrated is supported on a table 10 which in turn rests on suitable legs or other supports, which are not shown. The hat supporting part of the machine is constructed to support the hat so that it can rotatm so that it can. slide while it is-rotating andean also be swung.

The form of structure illustrated comprises a standard 11 which is arranged with the hub 12 in the bearings 13011 the table so that it can be swung by means to be hereinafter more fully described, and has at the top thereof a bearing 14 in which the shaft 15 rotates, the shaft 15 being driven by gears 16 and 17 from a flexible shaft 18 which receives its power from the, main shaft 19 by means of the gears 20 and 21. The block 22 is usedto hold the hat 23 and is made so as to approximate theshape and size of the crown when it is shaped or taut. Since the .hat is formed before it is clipped this machine, the brim 24 extends transversely or laterally from the. hat block, as will be clearly evident from Figures 1 and 3; -The bracket 25 is secured to the standard 11, the bracket: having on its extremity a bearing 27 for the end of the shaft 15, the

shaft being. secured by feathers or other means for permitting its sliding longitudinally relative to the gear 16 and also the gear 28, which isin mesh with the gear 29, which gear 29 is on a supplemental shaft 'withthe cam 30 which cam'3O has a groove 33 which receives, the roller 31 arranged be; tween the collars 32, one at; least of these collars being arranged so that it saddles the top of the cam and is thus prevented from arranged so that they can be brought to bear on the hat to clip its surface, the preferred arrangement "being to arrange one clipping device 34 sothat it operates on the top of the brim 24, that is, the upper surface oft-he brinnaand is adapted to be'swung away from said brim and'also broughtbaek to the brim by the arm 35"pivoted at 36 and actuated by a cam 37 on the jack shaft 38,

i this jack shaftbeing driven from theirna in shaft bymeans of the gears 39 and 40.

A si m'i-lar clipping device *41 is arranged -at a place so that it willcliptliebottom face of the brim and is mounted on anarm 42 i actuated by a cam43-onthejack shaft38,

and a clipping device 44 for the crown-is mounted on arm-45*atnd is actuated by the cal-H146. These clipping devices "will be described in detail hereinafter.

The hub 12 of thestandardll is provided with means for swinging it through an 48 and resting in the slot 49 ofthe'bar 50, which bar has-aroller 51 on theend of it angleof 'at -l'east ninety degrees-the form shown comprising a crank '47"having a pin which is-arranged' in thes'lot52' of the cam 53 on the jack shaft" 38. "The whole device is operated throughsuitable belting arranged over the'fast pulley 54 and theloose pulley 55. Any suitable stopping'and starting means, either manual or automatic, can be installed to regulate the'starting and stopping of the machine.

The clipping devices .areshown in detail in Figures 58 and comprise a casing 56 which has a top plate 57 which hasanopening .at'thetop and towhichis attached an outlet pipe '58'by suitable means, such as a union connection 59, to which it 'attacheda hose.60 (see Fig. 1), which is attached to any suitable source of'suction so that the clippings from the fur are withdrawn and do not'float about in theair to the detriment of the health of theoperator.

:The casing 56 isj'provided onone end with abearing GO for one end ofthe shaft 61. The other end of the shaft, as at"62,'is'arranged so that it "issupported by a bearing plate 63, whiclrbearing, plate is substantially flat andis'fastened screws 641on its rearend and hasa bearing 65"for the shaft 6l,and has a lug'66 into which the bolt 67 is The shaft 61 is operated by means of a suitable flexible shafting 70 which prefer ably has its end 171 fastened in the end of the shaft by means of a screw or other fastening placed in the hole 72. A rocking ,plate 73ahas secured to its front end-a cut- --ter-bar -74, which cutter bar has its. front edge75-adapted: to be engaged by the: blades of the rotary cutter 69 to clip the material of the' hat, and to compensate for wear on the cutter and cutter plate the rocking plate 73-is adjustable in bearings, wh-ieh bearir-igs i-n turn-are adjustable. For this purpose the rocking plate 73 is provided with bosses74 onitsentls, these being recessed each to receive a ba1175 which permits the boss, and consequently'therocking plate, to rock on the ball, the stem 7 6 of the ball being supported'by a: spring'77, the tension of which isadj-ustable by means of the nut'78-screw-' threaded on thestem 76, the lower'end ofthe spring abutting on' the'bottom 79 ofa screwthrearle'd sleeve 80 having. a suitable head or finger piece '81.

The rocking plate'can be designed so that its cutting plate has'its cutting edge properly' po'sitioned'relative to the rotary cutter 69 by means of a strand 82 which extends throughthe supporting element 83, -which can be eithera handle or one of the arms 35, 42 'or45,"and is provided on its end'with a nut 84. On the other end it has a head 85 placed :in the post '86 of the rocking plate 73, and'a'spring87 holds the rocking plate in its adjusted positions, but with a resilience which makes it possible to give the end of the. cutter plate 74 a'fine' adjustment as-to its; pressure against the rotary cutter.

I prefer to providemeansfor roughing up thefur, onemeans comprising a set of steel or similar spring wires 88 fastened by a strip'89" or "by other means to thefront' of the frame, and a plate 90 extends down from the bottomof the" top 1 plate to nearly the bottom of the machine to provide only sufficient opening "for the strands of the'velour tobe clipped.

"It'willbe evident from Figure 6 that the material, as at 91, is closely matted very often "and it is'sufficiently scraped by the wires 88 to'loosen it andto'raise it-to a considerable extent, as at 92, but the suction of air enteringitheicasing, due to its being exhauste'd "through the pipe 60, causes 7 the velourfto stand up, as at 93, so that a substantiallyeven cut is provided over the entire surface of the hat. To insure such suction of air through the opening at the bottomof the casing Iprovide a plate 94, usually made of spring brass and'extending from one-side of the frame to the other, which bears against or substantially close to a shoulder'95 on the front part of the IOOklIlg plate;

It Willb'e evident that as the cutting edge hat, since the 75 wears down the rocking plate 73 must be readjusted, which can be done by turning the sleeve 80, which is screw-threaded in the casing, and this without altering the pressure of the spring 77, which spring insures at all times a proper and tight seating of the bosses 74: and consequently of the rocking plate in the frame. It will be evident from an inspection of Figures 1 and 3 that the flexible shafts 70 and the pipes can be provided with sufficient slack so that the arms 35, 42 and 45 can be swung without affecting the operation of these parts.

Theoperation of the device is as follows:

lVheIi the machine is ready to start, the cams 37, 43 and 46 are in such position as to swing the clipping means down away from the hat, or rather the hat supporting block 22, and then the hat 23 is As the machine starts these: cams operate to swing the clipping devices into position. those embracing the brim having guide plates, as 96, on the clipping device 41, and as 97 on the clipping device 3 these plates being preferably made of brass and having curved ends so as to receive the edge of the brim into the open mouth and then guide it between the cutter plates 7st and each of its guide plates, these guiding plates also acting to hold the brim into position while it is being out. As these clipping devices take position the hat is rotated by means of the mechanism hereinbefore described for at least one complete rotation, and then the can1s37 and 43 operate to swing the brim clipping devices 34 and 41 away from the clipping of the brim is now completed. a

The clipping device 44 that is clipping the crown remains in position and the cam 30 now begins to slide the hat backward, since the shaft 15 is pulled backward, and as this backward movement begins the cam 53 operates to swing, through the crank 47, the standard 11 so that the hat slowly assumes the position shown at a in Figure 4, that is, it is half way around, having turned about forty.tive degrees, the turning point being substantially in line with the center of the clipping device A l, and this continues until the hat arrives at the position shown at b in Figure 4, which is at right angles to the position the hat originally was in. As this is clipped the cam 46 acts to A ping device H away from the hat and the cam 56 operates to swing the arm 11 back to its normal position and the cam 30 acts to push the shaft 15 and the hat that it supports back to its normal position. and the hat can be removed from the machine and another but substituted for a repetition of the above described steps.

It will be understood that minor details can be altered, and that parts can be differently assembled and proportioned, without put in place.
